.To @ZZ whom, il may concern:

Be it known that I, GEORGE T. SMITH, a citizen of the United States,residing at Jackson, in the county of Jackson and State of Michigan,have invented certain new and useful Improvements in Flour -Bolts, ofwhich the following` is a specification, reference being had therein tothe accompanying drawings.

Figure l isa side elevation, partly in section, of abolting-reelcontaining myinvention. Fig. 2 is an end view, a portion of the casingbeing broken away.

I have shown myinvention as being applied to a centrifugal reel; but itis apparent that it may be used in connection with many other types orforms of bolting-reel; hence I do not wish to be limited by theconstruction herein shown.

I have shown the reel as being mounted in an ordinary frame work, withan inclosing casing, gatherboards, and conveyers of the usualconstruction, and which need not there fore be specifically described.

In the drawings, A is the centrifugal beatcrshaft, through which poweris applied for the purpose of operating the beaters and the rotatingreel.

B O are the reel-heads, and I) D the longitudinal ribs, which extendfrom one reel-head to the other, as is customary in this class ofmachines. The reel-head Bis substantially fiat upon its outer face,except that it is grooved near its periphery, thusleaving a rib or bead,b, around its outer edge.

E F is a flanged ring of such internal diameter as to tit closely theperiphery of the head C, which latter is dat upon both sides, exceptthat, by preference, it is constructed with a series of bosses, c c,upon its inner face, the bosses being arranged in a circle, of which thebeater-shaft is the center. This head is provided with a series ofholes, each extending through the head proper and through one of thebosses o.

G- G are draw-bolts fastened through the holes in the heads and thebosses c, and into screw-threaded holes formed for their reception inthe flanges or ears E of the ring.

g g are clips or clasps, each attached at one end to the baiting-cloth,and adapted to enclean,I have devised the following mechanism:

K is a rock-shaft mounted at both ends in the easing, and havingbrush-carrying arms L L keyed thereto near each end Ljust inside thecasing. Misa rocking arm keyed to the rockA shalt outside the endcasing, with its lower end extended down into the path traversed by aseries of pins, n, preferably two or more, which project horizontallyfrom the vertical face of a wheel, N, which isattaehed to and carried bythe outer end of one ofthe eonveyershat'ts O. P is a retraetingspringhaving one end secured to the casing or the frame ofthe machine, and itsopposite end attached to the brush, or to one ofthe rocking arms L, asmaybe preferred, so that at each revolution ofthe conveyer-shaft anumber of reciproeations will be imparted to the brush.

It will be seen that the pinsn act as stops to prevent the spring I fromdrawing the rocking arin M too far to one side, in which ease the pinswould fail to act upon it as they move around with the wheel N.

Then preferred, the spring I may be attached to the rocking arm M, andsome other form of spring might be substituted for the spiral shown inthe drawings.

I have shown and preferto attach one end of this spring I to thebrush-back and the other end to one ofthe gather-boards, as thisarrangelnent insures that the spring shall work advantageously, shall beentirely concealed and protected, and that there shall always be somestationary part ofthe machine (the gather-board in thisinstance) towhich one end of the spring may be readily attached, whatever be theposition of the spring longitudinally of the reel; or, when preferred, aweighted arm projecting at an angle from the bruslrarms L L might beemployed to return the brush to its normal position after the rockingarm has been moved by one of the pins n.

Ido not claim,broadly,the eombination,with the outer surface of areel-bolt, of a brush arranged longitudinally and mounted upon rockingarms so as to sweep the cloth, as I am IOO aware that such constructionis old; but my construction of devices possesses some advantages overany other of which I have knowledge. ForA instance, imparting theswinging motion to the arm M in one direction by means of pins nprojecting from the wheel N,and imparting a return motion by means ofaspring or Weight, permits the employment of plate N or its equivalent,havingthe pins attached thereto, under circumstances where a crank-pinprojecting from the wheel and pitman connecting I the crank-wheel with arocking arm could not be used, it being apparent that the operation ofmy devices would not be interfered with in case .a belt were applied tothe conveyer-shaft outside of and ina plane parallel with the wheel Nfor the purpose of turning the conieyers, whereas it would be impossibleto en1- ploy a crank-pin and pitman in connection with this plate N weresuch a drivingpulley employed. So, also, in case it were found desirablefor any reason to arrange the plate N and arm M inside the casing of themachine and of the bearing of the conveyer-shaft, my devices wouldoperate, while it is apparent that a crank-wheel and pitman cannot beemployed in such arrangement of parts.

IV hat I claim isl. In a Hour-bolt, the combination,with the bolt-cloth,of the rock-shaft, the brush s upported upon the rockshaft, a plateatt-ached to and carried by the conveyer, a pin projecting horizontallyfrom the face of the plate, an arm connected to the rock-shaft andactuated by the pins, and a spring for moving the rock-shaft and brushin one direction, substantially as set forth.

2. In a iiour-bolt, thc combination of the bolt-cloth, the rock-shaftmounted in the casing and having one end projecting outside thereof, abrush supported upon the rockshaft and arranged to sweep the bolt-cloth,

an arm, M, connected to the end of the rockshaft outside of the casing,and projecting pins carried by the conveyer arranged to engage with armM, and through it to move the brush, substantially as set forth.

3. In a our-bolt, the combination of the bolt-cloth, a rock-shaftmounted in the casing and having one end projecting outside thereof, abrush supported upon the roclcshaft and arranged to sweep thebolt-cloth, an arm, M, connected to the end of the rock-shaft outside ofthe casing, pins u, which move the arm M and the brush in one direction,and a spring which moves the brush in the opposite direction,substantially as set forth.

4. In a Hour-bolt, the combination of the boltcloth, a rock-shaftmounted in the casing and having one end projecting outside thereof, abrush supported upon the rock-shaft and arranged to sweep thebolt-cloth, an arm, M, connected to the end of the rock-shaft outsideofthe casing, pins n, which move the arm M and the brush in onedirection, and a spring, P,within the casing,and connecting thebrushback with some stationary part of the machine, substantially as setforth.

5. In a flour-bolt, the combination of the bolt-cloth, a rockshaft, abrush supported upon the rockshaft and arranged to sweep the bolt cloth,an arm, M, vkeyed to the rockshaft, pins which move the arm M and brushin one direction, a spring which moves the brush and arm in the oppositedirection, and a stop which limits the movement of the arm caused by thespring, substantially as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

GEORGE T. SMITH.
